I left my PC to watch TV for a while, and when I came back after over an hour, the PC was idling and the screen was in standby mode. So far, so good, works as intended (30 mins -> screen off). Then I noticed the GPU had clocked from 23 MHz to 850 MHz, and RAM was at 1000 MHz. The clock rates returned to idle values once I reactivated the PC/screen. I have a Strix Vega 64 and I'd expect clocks to remain at desktop idle level once the screen is off. Any ideas what could be causing this behaviour?
